    Don't wanna sound like a wiseass here, but when you ask your valve train to do more than it was designed to do, generally, you start finding the chain of "Weak Links" . . Performance demands longer Valve opening times (duration) and greater Openings (Lift). The duration won't hurt much, but lift will kill you . .

    Springs, keepers and rocker studs are gonna know you're trying to "Cheat" on 'em . .

    If you want to sound bad at a stoplight, pull a plug wire and take off the muffler. If you want it to get on the tire, get out the wallet and don't get too crazy with the lift . .

    Super Chevy has a current series article called modern mouse. Lot of information no matter how biased it is.
    This wouldn't have happened if only you had been paying attention!
